Iains - this may be a bit of a fatalistically 'out there' idea..
but maybe we all do need to be exposed to the virus eventually,
over organized co-ordinated stages planned for by region and time...

similar to childhood 'measles parties'...

It's a lottery which of us will survive, but it will get the threat out the way with,
and probably build up a greater level of mass immunisation
before a vaccinate is miraculously discovered
by profiteering pharma corporations...?????????????????????????????????

I emphasise..????????????????????????????????????????????????...
